I am looking at the docs here - Default Auth0 Error Page
If your callback URL is valid, when an authorization error occurs, the Authorization Server returns the appropriate error and state parameters to your callback URL.
I have added a url to “Allowed Callback Urls” in my application settings, I have also tried both the Default/Custom Error page options in Tenant Settings.
I still receive a black error page when viewing an expired link. All other topics I have come across on the community board remain unresolved. I am working on an inherited implementation for a Next.js web app.
Hey @stellar !
I see the checks.state argument is missing error is occurring. I found some solved community posts that may be able to help you.
Hey All,
I find that every so often(not sure of the exact cadence for this error) I get the following error after the user is successfully authenticated(i.e. the url this is happening on is https://website.com/callback ):
BadRequestError: checks.state argument is missing:

### Description
Sometimes while testing this I get:
```
BadRequestError: checks.state argument is missing
at <folder>/node_modules/express-openid-connect/middleware/auth.js:105:31
at processTicksAndRejections (internal/process/task_queues.js:97:5)
```
This happens randomly after logging in.
### Reproduction
It happens especially often at the first login, but sometimes just randomly after logging in. My code:
```js
require('dotenv').config()
const express = require('express')
const app = express()
const { auth } = require('express-openid-connect')
const config = {
authRequired: false,
auth0Logout: true,
issuerBaseURL: process.env.ISSUER_BASE_URL,
baseURL: process.env.BASE_URL,
clientID: process.env.CLIENT_ID,
secret: process.env.SECRET,
}
app.use(auth(config))
app.get('/', (req, res) => {
res.send(req.oidc.isAuthenticated() ? 'Logged in. Welcome!' : 'Logged out. <a href="/login">Login?</a>')
})
app.listen(3000)
```
### Environment
- **Version of this library used:** 2.0.0
- **Version of the platform or framework used, if applicable:** Express version 4.17.1
- **Other relevant versions (language, server software, OS, browser):** Node.js version 12.18.4 installed with nvm, macOS 10.15.6, Chrome 85.0.4183.121
- **Other modules/plugins/libraries that might be involved:** dotenv version 8.2.0
I hope this helps!
Best,
